Why Did Tech Companies Abandon Removable Batteries?
EU regulations might bring back user-replaceable batteries in the near future.
1Reasons behind the decline of removable batteries
Tech companies moved away from removable batteries to create thinner and more durable devices. When Apple introduced its 17-inch MacBook Pro with a fixed battery in 2009, it defended the decision by claiming it allowed for extra capacity. Removable batteries require additional protective layers and take up more internal space. Fixed batteries, on the other hand, maximize space utilization and offer longer battery life.
2Historical context: Batteries in older devices
In the 1990s and 2000s, removable batteries were standard in phones, laptops, and portable gaming consoles like the Nintendo 3DS. With slower charging speeds at the time, users preferred carrying spare batteries. Nickel-metal hydride and nickel-cadmium batteries also had disadvantages like memory effect, making removable batteries more practical.
3Advances in modern battery technology
Lithium-ion batteries largely solved issues like memory effect and self-discharge. Materials like silicon-carbon with high energy density enabled high-capacity batteries in slim devices. Fast charging technologies and accessories like power banks also reduced users' battery concerns.
4The EU's new regulations
The EU will require user-replaceable batteries in portable devices starting February 18, 2027, with exceptions for smartwatches and fitness trackers. This rule covers phones, headphones, and portable gaming consoles. Sennheiser has already adapted its Momentum 5 wireless headphones to comply with these regulations.
5Companies adapting to the changes
Nintendo will launch its new Joy-Con 2 controllers with replaceable batteries this winter. It also plans a new version of its Pro Controller with a swappable battery. Some phone models like the Fairphone 6 still offer removable batteries. EU regulations could have far-reaching effects on the tech industry.
6Advantages of removable batteries
Removable batteries can extend device lifespans and reduce electronic waste. Users won't need to replace entire devices when battery performance declines. Having spare batteries also extends usage time in emergencies. These features offer significant sustainability benefits.
7Arguments for fixed batteries
Manufacturers argue that fixed batteries allow for lighter and waterproof devices. Fixed batteries are seen as safer for devices with IP67 water and dust resistance ratings. They're also claimed to offer better charging efficiency and battery life performance.
8Future trends and implications
EU regulations might lead to a resurgence of removable batteries. However, this change will require significant redesigns of devices. Manufacturers must plan how to meet removable battery requirements while maintaining slim and durable designs. Consumers may face choices between sustainability and convenience.
